ALBERT DU oN'r, OFMAILE CITY, MICHIGAN;

- 7 VALVE,

- Application filed February Be'it known that I, A BERT DUMONT,

citizen of the United .States, residing ,at

Maple City, in the county of Leelanau and provision of a valve mechanism which in State of lilichigan, have invented new and useful Improvements i1'i;Valves, of which thefollowing is a specification.

This invention relates to improvements in valve mechanisms especially adapted for s toilet flushing-tanks and the like, an object being toprovide a valve which will effectually preventleakage of water through the discharge port of the tank and which may be readily opened and automatically closed.

Another object of the invent-ion is the provision of means'for automatically opening the valve when water-within the tank reaches apredetermined level and thus'prevent overfiow of the tanln- 1 a l Another object of the invention is the addition to the above andother advantages, is simple in construction, efiicient in use and" in whichaccess may be readily had to the various parts for adjustment and repair.

lVith the above and other objects in view, the invention further includes the 'following novel features and details of construction, to be hereinafter more fully described. illustrated in the accompanying drawings and pointed out in the appended claims.

In the drawings f Figure 1 is an elevation partlyiin section showing a portion of a. tank or container with the invention in position for use.

Figure 2 Figure 1.

Referring in detail to the drawings wherein like characters of reference denote corresponding parts, the reference character 10 indicates a portion ofa container such as the usual flushing tank, the latter being provided with an outlet opening in which is secured a fitting 11. The inner end of this fitting is provided with an extension, the bore ofwhich isoutwardly flared so as to provide an annular inclined valve seat 12 through which the tank is discharged and which is controlled by a valve 13. This valve is provided with a rubber or other compressible disk 14 which is beveled to enis a section on the line- 22 of gage the-valve seat 12 and is hingedly secured as indicated at 1 5 to a bracket 16 carslides the-stem '34 of a float-35.

@1925. Serial No; e,s4 0. I Y' ried by arod. the latter being secured which extends from the" within a lug 18 fitting 11s. I Extending 19 atthe outer end of which there "is secured a weight 20,, the latter acting to auto- ;matically close the valve'and hold the same an closed position,

Also extending from from thevalve13 is an arm the valve 13 is an arm 21 whose outer end'is 7 provided with an eye or enlargement 22. This arm passes through an eye 23 carried at' one end of one arm 24 of a bell crank lever, the latter being mounted for pivotal inovementin-an extension 25 ofthe bracket 3 16. 1 The other arm '26 of the bell crank lever has secured thereto one'end of a 'roi 27 and the opposite end of this rod is, se-

oured to an arm 28 which-is rigid with the.

inner end of a short shaft 29-inounted in' a" suitable bearing plate which extends [through one'wall ofuthe container 10. The

'outer end of the shaft 29 is provided with anoperating handle 30.

Through, the medium the handle 30,

the shaft 29 may be rocked so to move 7 the bell crank lever pivotally through the This movement will connecting rod 27. lift the valve 13 so as to permit of the discharge of water from the container and when the operating handle 30 iszreleasedthe i under valve will be automatically seated the action of the weight 20.

Secured to a bracket 31 carried by the 7 rod 17 is aguide 32. This guide is provided with spaced eyes 33'through. which The sten:

34 is also slidable through an eye 36 carried vat theupper end ofvanarm 37, the latter beingi pivotally connected to the valve 13' as'indicated at 38. The lower end of the rod 34 is provided with an eye or enlarge ment 39.

Vhen the valve 13 is opened in the 1nan-- her just described, the arm 37 will slide along the stem 34 without interfering with the operation of the valve or. causing any movement of the fioat 35. Should water within the tank 'or container rise above the lower flatface 40 of the float 35,the latter j will open the valve 13 and permit a sufficlent' amount of water to escape through the discharge opening and prevent overflow of the tank.

The invention is susceptible of various changes in its form, proportions and minor details of construction and the right is herein reserved to make Sllflll-CljiitllQQSfZl'S:PIQPQIl'Y fell *ithin the scope of the appended claims.

Having described the invention What is claimed is:

' 'lhe combination with :1 container hava clischerge outlet, nornmlly closed ve for controlling the outlet, nirenuel'ly operated means to open the valve, a vere-ieelly movable stem, a guide for the stem,

at carried bvtlie stem end a link l1avone end p 'ts opposite ally connected to the valve end slldingly connected with said stem to open the valve when liquid Within the container reaches a predeterlinined level.

2. The combination with a container hav mg a discharge outlet, a pivotally mount-- ed normally closedwveighted valve for controlling the outlet, a pivotally mounted bell lcrank lever, means to move the lever pivotelly, means connecting the lever and valve to open thevelve when the bell crank lever is operated and permit said valve to open independent Ofil16' 111()V1110I1t of the hell crank lever and iloet operated means connected t'o the valve to open the letter when liquid within the container reaches a predetermined level.
